TPA3118D2 IC SMD (Audio Amplifier)
Non-returnable
BD 6.500
The TPA31xxD2 series are stereo efficient, digital
amplifier power stage for driving speakers up to 100
W / 2 Ω in mono. The high efficiency of the
TPA3130D2 allows it to do 2 × 15 W without external
heat sink on a single layer PCB. The TPA3118D2 can
even run 2 × 30 W / 8 Ω without heat sink on a dual
layer PCB. If even higher power is needed the
TPA3116D2 does 2 × 50 W / 4 Ω with a small heatsink attached to its top side PowerPAD. All three
devices share the same footprint enabling a single
PCB to be used across different power levels.
The TPA31xxD2 advanced oscillator/PLL circuit
employs a multiple switching frequency option to
avoid AM interferences; this is achieved together with
an option of either master or slave option, making it
possible to synchronize multiple devices.
The TPA31xxD2 devices are fully protected against
faults with short-circuit protection and thermal
protection as well as overvoltage, undervoltage, and
DC protection. Faults are reported back to the
processor to prevent devices from being damaged
during overload conditions.
